Just had my oil changed and radiator flushed. Check engine light came on next day so had them run a diagnostic. Codes PO300 and PO153 show up.

I know what the codes are but what would you recommend I do to try and solve for one or both and in what order would it make most sense?

Did the engine get wet

I would have it checked for tune up /coil
, check if have an exhaust leak
check fuses
check if any the wires touching the exhaust and or cut and shorted
replace the suspected O2 sensor if all tested OK
